Answer: The coefficient in front of nitric acid is 2
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas. Liquids are represented by (l) and gases are represented by (g).
The balanced chemical reaction is :
*Go into solution
*Break down
*Liquefy
*Disintegrate
*Melt away
*Evaporate
*Dissapear

Answer:
Explanation: Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.
Answer:
The correct answer is "D. The difference in their electronegativities is greater than 1.7"
Explanation:
An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.
So, this type of bond consists of the attraction of atoms with electric charges of different signs, that is, the bond is established when atoms of low electronegative elements (metals) are bonded with atoms of highly electronegative elements (nonmetals).
So you can say that atoms of electronegativity difference equal to or greater than 1.7 participate in this type of bond (with its exceptions).
<u><em>The correct answer is "D. The difference in their electronegativities is greater than 1.7"</em></u>
